The Tibetan Plateau is highly sensitive to climate change. Knowing local Tibetans’ perceptions of climate and ecological changes is important for exploring the climate and vegetation changes in this vast and remote plateau. We interviewed residents in three counties, Dege, Seda, and Ruoergai, on the eastern Tibetan Plateau and analyzed their perceptions of climate and ecological changes; then, we compared the results with those from instrumental observations. The results showed that residents are sensitive to changes in temperature and extreme weather, and the perceptions of temperature change are consistent with meteorological observations. Both remote sensing observations and local perception showed an advanced green-up date in the eastern Tibetan Plateau. More than half of informants perceived an earlier start date and a later end date of Ophiocordyceps sinensis harvesting, which indicated an advance of vegetation spring phenology and a possibly upward distribution extension in elevation under climate warming, respectively. The results also indicated that it is necessary to explore the vegetation phenology of the Tibetan Plateau from the perspective of sub-regions. More research on the views of environmental change should be carried out in different sub-regions of the Tibetan Plateau, and the interrelationship between perceptions is also worth exploring.

青藏高原东部当地居民对气候和生态变化的认识

青藏高原对气候变化高度敏感。了解当地藏人对气候和生态变化的看法，对于探索这个广阔偏远高原的气候和植被变化非常重要。我们采访了青藏高原东部三个县德格，色达和若尔盖的居民，并分析了他们对气候和生态变化的看法。然后，我们将结果与仪器观测的结果进行了比较。结果表明，居民对温度和极端天气的变化敏感，对温度变化的感知与气象观测结果一致。遥感观测和局部知觉都表明青藏高原东部的绿化日期提前。超过一半的线人认为更早的开始日期和更晚的结束日期中华麦冬的收获表明，在气候变暖下，植被春季物候的发展和海拔高度可能向上分布的扩展。研究结果还表明，有必要从分区域的角度探讨青藏高原的植被物候。应该在青藏高原的不同分区进行更多有关环境变化观点的研究，并且在观念之间的相互关系也值得探讨。
